REPEATIN G SHOTGUN.

Application filed April 6,

The present invention relates to fire arms, particularly of the magazine type, and has particular reference to an improvement in the mechanism for unlocking the action of a repeating shot gun.

An object of this invention is toprovide an improved construction of unlocking mechanism wherein the movement of the main spring is utilized to unlock the action after firing.

Another object of the invention 1s to provide an unlocking action which is adapted particularly for use in connection with a repeating shot gun, particularly of the type known as models 520 and 620, manufactured by J. Stevens Arms Company, of chicopee Falls, Mass, and illustrated in their catalogue No. 56, and manufactured under patents to J. M. Browning, No. 781,765 of February 7, 1905, and No. 864,608 of August 27, 1907, for magazine guns, the present invention reducing the number of unlock ng parts required and automatically releasing the slide by the rising action of the main spring in impelling the hammer toward fir ing position.

Briefly stated, the invention embodies a peculiar construction of the slide lock or safety bar and the slide release button, and its stud associated with the slide lock, so that the slide look and the slide release button may be moved to a releasing position by the rise or relaxing of the main spring, the release of the slide being effected immediately after firing and to allow the operating handle bar to be drawn back to eject the tired shell.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more par; ticularly pointed out in the claims appended hereto. 1

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a fragmentary left side view of the firing and locking actions of av repeating shot gun, the parts shown in fired position and with the slide released;

Figure 2 is a similar view, but with the parts in locked position and ready to fire;

Figure 3 is a like view, showing the parts in position in'nnediately after firing and wherein the slide is released and the slide release button raised;

Figure 4 is a view similar to Figure 2, but

showing the right side of the trigger and release actions ready for firing;

Figure 5 is a fragmentary top plan view of the heel of the slide lock bar, with the slide release button and its stud, showing the latter overhanging the main spring;

Figure 6 is a detail side elevation of the slide lock or safety bar; and,

Figure 7 is an edge view of the slide release button, showing the connecting and spring engaging stud carried thereby.

Referring to the drawings, 10 designates the frame of a shot gun to which the barrel is attached and which is provided with a magazine section 11, having an operating slide 12 for feeding cartridges intp the loading chamber and for ejecting the empty cartridges after firing. The frame 10 carries the usual firing pin 13 in position to be struck by a hammer 14 provided on its up per end with the usual hook portion 15 and pivoted at its lower end at 16 upon the trigger plate 17. The hammer 14 is provided with a shoulder at its inner end, in which is seated an anti-friction roller 18, adapted to bear upon a main spring 19 carried by the plate 17 and used for operating the hammer14. A trigger 20 is mounted on a pivot 21 on the trigger plate 17 andhas a hook portion 22 for interlocking engagement with the hook portion 15 of the hammer 14, to hold the latter in position, ready to fire.

Also mounted upon the pivot 21 of the trigger plate 17, is a slide lock or safety bar 23 of angle formation and provided with a long arm having a nose 24, adapted at times to seat in a socket 25, provided in the downwardly extending rear end of the slide 12, to lock and hold the slide against back- J ward movement. The slide lock or. safety bar 23 also has at its upper edge and intermediate its long arm a shoulder 26 adapted to interlock with a lug 27 on the side of the hammer 14, for holding the latter in retracted position, until the slide lock is released. The hee'l portion of the slide lock is provided with an arm 28, which is of sufficient length to extend upwardly beyond the horizontal plane of the main spring 19. and which is provided in its upper end with an aperture 29, through which projects a stud 30. The stud 80 is mounted upon a slide release button 31, in the form of an elongated fiat bar, which is suspended from the stud and extends downwardly through the trigger plate 17, adjacent to the trigger and is knurled or otherwise suitably formed on its lower end for engagement by the finger to raise the slide release button 81. The stud extends inwardly from'the slide lock 23 and across the main spring to an-extent which is sufficient to give the stud 30 a bearing surface on the spring, so that the spring 19 in rising, lifts the stud 30 therewi h and also the slide release button 31.

In operation, with the parts in position to fire, as shown in Figures 2 and 4:, the hammer 1a is interlocked with the trigger 20 and the slide lock or safety bar 23, not only looks the hammer 14 against accidental release upon movement of the trigger, but also engages the slide 12 to hold the latter from being moved back accidentally. When the trigger 20 is drawn back, the hammer 14 is released and swung upwardly and forwardly against the firing pin 13, by the main spring 19. The spring 19, in rising to operate the hammer 14, engages the stud 80 and lifts it together with the slide release button 31 and the rear end of the slide lock or safety bar23. The result is that the nose 2a of the slide lock is released from the slide 12 and the unlocking is effected automatically by the main spring 19. It will be noted that the structure is such that it does not interfere with the manual release of the slide lock, and the slide lock is held by the main spring in released position, so that the action cannot be accidentally locked during the handling of the gun.

It will be obvious that changes in the con struction, combination and arrangement of parts could be made, which could be used without departing from the spirit of my invention, and I do not mean to limit the invention to such details, except as particularly pointed out in the claims.

l-Iaving thus'described my invention, what I claim and desire to secure by Letters Patent of the United States is z- 1. In a repeating gun, the combination with a hammer, a tri ger for releasing the hammer, a main spring for operating the hammer into firing position and an ejector controlling slide, of a. slide lock adapted to interlock with said slide to hold it from movement, a slide release button, and a stud connecting said button with said slide lock and projecting beyond the same and into the path of said spring, said spring adapted upon movement of the hammer into firing position to engage said stud and shift the slide lock'into releasing pos1t1on.

2. In a repeating shot gun having a main spring, a hammer adapted to be moved thereby into firing position, and an ejector controlling slide, a pivoted slide lock of angle form having one end for interlocking engagement with said slide to hold it from movement, a slide release button for the other end of said slide lock, and a stud pivotally connecting said button to the slide lock and having an extension projecting over said main spring, said main spring adapted to engage and lift said stud upon the movement of the hammer to liring position for automatically shifting said slide lock to release the slide.

An unlocking for repeating shot guns having the usual main spring, hammer and ejector controlling slide, comprising a pivoted slide lock having a long arm adapted to interlock with the slide and having a short arm of sul'licient length to extend above the main spring and provided with an opening therethrough, and a slide release button provided with a laterally extending sti 1d at its upper end for engagement through the opening in the slide lock and into the path of said main spring, said spring adapted to elevate said stud and swing said slide look into unlocking posiion when the hammer is moved to firing position. 7

4. An unlocking actionfor repeating shot guns comprising a slide lock having a long arm with a nose for interlocking engagement with the slide of the shot gun and having a short, arm adapted to project above the transverse plane of the main spring of the shotgun, a. slide release button, and a stud connecting the button to the short arm of the slide loci said stud having an extension projecting beyond the button and the slide lock into position over said main spring of the shot gun, whereby upon the expansion of the main spring to lire the shot gun, the main spring may engage and lift said stud and swing the slide look into unlooking position.
